YARN-PROTECTOR ATTACHMENT FOR SPINNING-FRAMES.

SPECIFICATION forming part of Letters Patent No. 628,875, dated July 11,1899.

Application filed November 6, 1896. fierial No. 611,236. (No odel.)

To all whom it may concern:

Be it known that we, JOHN C. \VALL and MICHAEL E. SoHEDLBA'UER, J r.,citizens of the United States, residing at Amsterdam, in the county ofMontgomery and State of New York, have invented a new and useful YarnProtector Attachment for Spinning-Frames, of which the following is aspecification.

Our invention relates to an improved at tachment for spinning frames;and it is designed for use on that class of frames employing a movablering-rail and a series of rings which furnish the supports for loosetravelers that follow the threads as they wind on the bobbins.

The object that we have in view is to provide an attachment which servesas an antiballooning device to take the balloon out of the yarn and toafford means which operates to assist in cleaning the travelenring fromaccumulations of lint and dust that may tend to clog the traveler-ringand interfere with the free passage of the yarn through the same.

Our improved attachment is designed to be fastened to a ring-railadjacent to the traveler-ring thereon, but entirely independent of saidtraveler-ring,whereby the attachment serves as a fixture on'thering-rail and enables the travelenring to be removed from the ring-rail.

In the art to which our invention relates it is frequently necessary tochange the traveler-ring and use different sizes of ring-travelers whena different class or size of yarn or cotton is to be wound on thebobbin. Our invention is applied to the ring-rail so as to be entirelyindependent of the ring-traveler, and thus the latter may be removed andanother ring applied thereto, so as to provide for the use oftraveler-rings of different sizes to suit the kind and class of yarn tobe wound on the bobbin.

Our improved attachment is simple and durable in construction, readilyapplied to the ring-rail of an ordinary spinning-frame with outinterfering with the traveler-ring or the traveler adapted to said ring,and the attach" ment is so applied to the ring-rail that a part thereoflies in juxtaposition to the traveler for the purpose of assisting inremoving accumulations of lint in the traveler.

To the accomplishment of the object of our invention we provide anattachment entirely independent of the traveler-ring andconsisting of asingle piece of wire bent to form a circular guard,an upright shanlganangular arm, and a fastening-prong. applied to a ring-rail by having itsfastening prong thrust into the ring-rail at a point adjaoent to thetraveler-ring, and the angular arm of the attachment is turned to bringthe upright shank in a position adjacent to, but out of contact with,the traveler-ring, so that said upright shank lies close to the path ofthe traveler, and the circular guard is maintained in the positionparallel to the travelerring and substantially in vertical alinementtherewith.

To enable others to understand our invention, we have illustrated thesame in the accompanying drawings, forming a part of this specification,and in which- Figure 1 is a perspective view of a portion of an ordinaryspinning-frame with our improved yarn-protector attachment appliedthereto in operative relation to a bobbin, a ring-traveler, and the ringon which said traveler is supported. Fig. 2 is a detail perspective Viewof the attachment removed from the ring-rail. Fig. 3 is a verticalsectional View of the ring-rail and adjacent parts, showing the preciserelation of the antiballooning and traveler cleaning attachment.

Like numerals of reference denote like parts in all the figures of thedrawings.

Referring more particularly to Fig. 1, the nu meral l designates thespindle-rail, and 2 the bobbin-spindle, on which is mounted an ordinaryyarn-bobbin 3. 4 is the movable ring-rail. 5 is the ordinary flangedring carried by the ring-rail and through which the bobbin extendsloosely,and 6 is the traveler,loosely fitted on the ring 5 and adaptedto fly rapidly thereon as the spinning of the yarn on the bobbinprogresses. The loose traveler 6 receives the yarn or thread 7 in theusual way, and said thread passes through a guide-eye 8 on the outeredge of the hinged guide-block 9, arranged with a series of similarblocks at the This attachment is front edge of the ordinary thread orguide board 10 of the spinning-frame, above which guide-board isarranged the usual set of drawing-rolls 11. All of these parts are ofthe usual and well-known construction, and no novelty theretois claimedin this application.

Our invention consists of the antiballooning attachment illustrated indetail by Fig. 2 of the drawings and as applied in operative relation tothe ring-rail,the traveler-ring, and thetraveler by Fig. 1. 12 is madefrom a single piece of stout wire, which is bent atone end to provide asubstantially circular guard 16, after which the wire is bent at rightangles to the plane of the guard 16 in order to form the shank orstandard 13, and then the wire is bent into the horizontal arm 14 andthe attaching-prong 15. The arm 14 extends substantially at a rightangle from the lower part of the upright shank 13, and the prong 15 isataright angle to the arm 14 to occupy a position substantially parallelto the shank 13, but-in a plane at one side of said shank 13. In ourinvention the guard 16 has its free end terminating at some distancefrom the shank or atthe point where the shank and ring are joinedtogether,and thus an enlarged throat or opening is provided in the guardat one side thereof. This construction of the guard overcomes thetendency of the thread to bulge out above or below the guard under thecentrifugal force of a high-speed spindle and insures proper coiling ofthe thread uniformly on the bobbin without any tendency of the thread toballoon.

It will thus be seen that we have provided a very simple yarn protectorattachment, which is bent from a single continuous piece of wire, andthis method of making the attachment provides for rapid and economicalmanufacture of the contrivance.

To apply our attachment to a spinningframe, it is only necessary to boreor otherwise produce a vertical aperture in the ringrail adjacent to thetraveler-ring, and into this aperture is driven the vertical prong 15 ofthe attachment. This prong 15 may be turned in the ring-rail to causethe arm 14: to occupy a position tangentially to the traveler-ring 5,and thus the arm serves to position the upright shank 13 adjacent to thetraveler 6, so that said shank occupies a position close to the path ofthe traveler sufii cient to intercept any lint or dust which may bethrown by centrifugal force beyond the periphery of the traveler,whereby the shank serves to assist the centrifugal action of thetraveler in removing accumulations of lint from said traveler, and thuskeep the latter in a free clean condition for the easy passage of theyarn-threads therethrough. The angular arm 14 at the lower part of theattachment also forms a driving-head to be struck for forcing the prong15 into the ring-rail and still further serves to stiffen or strengthenOur attachment the device by reason of its position between and angularrelation to the terminal prong and the uprightshank of the attachment,and thus the arm 1-l serves as a means for reinforcing the device and asmeans for properly positioning the shank 13 with relation to thetraveler. The guard 16 is sustained by the shank at a proper elevationabove the traveler-ring 5, and said guard is arranged in a planeparallel to that of the traveler-ring 5, so that the opening in theguard 16 is in substantially vertical alinement with the opening in thetravelerring. Said horizontal guard forms nearly a complete circlearound the bobbin which passes through the traveler-ring 5, and saidguard serves to restrict the play of the yarn as'it is carried with thetraveler around the ring 5 for winding on the bobbin to such an extentas to entirely overcome ballooning of the'yarn and to cause,

the yarn to be wound under uniform tension and reduce the breakagethereof to a minimum.

Our attachment serves important purposes in connection with a bobbin, atraveler, and a ring-rail, because the device serves to take all of theballoon out of the yarn in its passage from the drawing-rollers t0 thebobbin and to assist in keeping the traveler in a clean condition forthe-free passage of the yarn through the same. ,The device when attacheddoes not require attention on the part of the operator either to adjustit in proper relation to the travelewring or to the traveler or to cleanthe traveler from time to time, as is found necessary with ordinaryspinning-frames. Oneof theimportant feattures of our invention residesin the fact that the attachment is applied or fastened directly to thering-rail entirely independent of the traveler-ring thereon, and hencethe traveler ring may be disconnected from the ring-rail withoutinterfering in any Way with the yarnprotector attachment and withouthindrance therefrom, thus enabling the ring and the traveler to be remoed or replaced, as may be required, without disturbing the attachment.

In this connection it is to be observed that the provision of thecircular guard 16 with an enlarged side opening or throat next to thevertical shank 13 is an essential part of the device,as such enlargedside opening or throat permits the traveler-ring to be removedtherethrough, so that the traveler-ring can be slipped off of thespindle without disturbing the position of the attachment.

WVe are aware that it is not new, broadly, to provide a yarn-protectorwhich is applied to a traveler-ring; but so far as we are aware suchprior device requires a special construction of the traveler-ring forthe reception of the protector attachment and any adjustment or removalof the traveler-ring disturbs the relation of the protector attachmentto the ring-rail and the bobbin. attachment, constructed as described,avoids Our improved these objections and enables it to be used onspinning-frames without requiring a special construction of thetraveler-ring.

Having thus described the invention, what we claim is "In an attachmentfor spini'iing-frames, the combination with the ring-rail, thetravelerring carried thereby, and the traveler, of acombinedantiballooning device, and a traveler-ring consisting of a wirebody provided with a vertical shank having at its upper end a horizontalcircular guard-ring adapted to be disposed above and concentric with thetraveler-ring, one end of the guard-ring terminating a distance short ofthe horizontal shank to provide an enlarged side opening or throatdirectly at one side of the said shank,

said vertical shank terminating at its lower latter to removeaccumulations of lint and dust.

In testimony that we claim the foregoing as our own we have heretoaffixed our signatures in the presence of two witnesses.
